2005 Chevrolet Venture Parts Questions & Experts Answers

• Q: How to replace the A/C Accumulator in an A/C system on 2005 Chevrolet Venture?

  A: You should start by collecting refrigerant from the A/C system before you remove the condenser to change the A/C accumulator. First unfasten the lower A/C accumulator mounting bolts and upper bracket bolt before extracting the A/C accumulator while discarding its sealing washers. New A/C accumulators require PAG oil addition according to specifications before installation by using fresh sealing washers. Before installation of the A/C accumulator to the condenser, use appropriate fasteners according to their designated positions while keeping in mind that you need to select fasteners matching the necessary part number for proper functionality. Fluid application such as paints and lubricants and corrosion inhibitors should be avoided completely on fasteners and their joining surfaces since they impact torque and clamping force. The correct sequence of tightening along with specifications must be followed in order to avoid damage. The installation of A/C accumulator lower mounting bolts requires a torque of 6 Nm (53 lb in) before applying the same specification to the upper bracket bolt. You should reinstall the condenser then vacuum the A/C system before recharging it and finish by testing the component connectors with the Halogen Leak Detector (J 39400-A).
